The AK4125XF is a precision dual (mono/stereo) digital-to-analogue converter. It consists of two multi-bit current-output converters, an integrated low-jitter clock generator, and a 24-bit digital filter. This device is suitable for various digital-to-analogue conversions, including Hi-fi audio and photo sensor applications. This converter has an integrated digital filter is capable of providing excellent sound quality and high resolution with low noise and distortion. Additionally, this device also features a low power consumption, a low operating voltage, and a high speed response time.

This device has a wide range of application fields such as home audio, automotive audio, professional audio, and medical systems. It is suitable for signal conversion of multiple digital audio signal formats including A-Law, μ-Law, and Pulse-Code Modulation (PCM). The device can also convert digital signals received from USB, SPDIF, and Bluetooth sources. Additionally, the device can be used for medical imaging systems such as Ultrasound and Magnetic Resonance Imaging (MRI).

The main principle behind the AK4125XF is the use of two current-output multi-bit Analog-to-Digital (ADC) converters. The digital-to-analogue processing is then carried out by the integrated low-jitter clock generator. This clock generator is used to feed both the digital-to-analogue convertors (DAC) and the digital filter. The output of the digital filter is then sent to the A-Law and μ-Law converter. The output of the A-Law and μ-Law converter is then sent to a low-noise, low-distortion Class-AB output amplifier, where it is turned into an acceptable analog signal.

The AK4125XF also features a 24-bit Digital Filter (DF) providing interchangeable digital filter parameters. The df is optimised for minimal latency, minimalPass-band Ripple and minimal Stop-band Attenuation. The DF also provides minimum phase response and extends the effective SFDR of up to 128dB. The current output ensures that the AK4125XF is compatible with a wide range of analog loads such as the common low-voltage bipolar and capacitive loads.

In summary, the AK4125XF is a precision dual (mono/stereo) digital-to-analogue converter, suitable for various digital-to-analogue conversions, providing excellent sound quality with low noise and distortion. It is suitable for a wide range of application fields ranging from home audio, automotive audio, professional audio, and medical systems. The integrated low-jitter clock generator, and the 24-bit digital filter provide the device with high resolution, low-jitter, and low-noise performance. The current output of the AK4125XF also make it compatible with a wide range of analog loads.
